使用云端功能添加子项？ [英] Add child using Cloud Functions?

问题描述

如何使用云端函数在 .onWrite 之后添加子项？

和如何使用JavaScript API写入实时数据库。

How do I add a child after .onWrite using Cloud Functions?

Code skeleton:

exports.addNewValue = functions.database.ref('/messages/{pushId}')
.onWrite(event => {
// add child newValue: "randomValue" to the newly added key above

解决方案

If you want to update the database at the same location where the change occurred with some key/value pair:

event.data.adminRef.update({key:"value"})

I suggest also getting acquainted with the documentation for how to work with database triggers, and how to write to Realtime Database using the JavaScript API.
